     R 2  is hydrogen, alkyl or alkoxy, 
     R 3  is hydrogen, halogen, cyano, aryl or aryloxy, the aromatic ring being unsubstituted or substituted, or R 3  is heteroaryl, adamantyl, fluorenyl or cycloalkyl or cycloalkenyl, the radicals being unsubstituted or substituted,

The present invention relates to novel ortho-substituted benzyl carboxylates, their preparation and their use as fungicides.

It is known that N-tridecyl-2,6-dimethylmorpholine or its salts, for example the acetate, can be used as fungicides (DE 1 164 152 and 1 173 722). However, their action is unsatisfactory in some cases. It is also known that methyl α-[(2-phenoxymethylene)-phenyl]- or α-[(2-alkoxymethylene)-phenyl]-β-methoxyacrylate can be used as fungicides (DE-35 45 319.2 and DE-36 20 860.4). However, their action is unsatisfactory.

We have found that novel ortho-substituted benzyl carboxylates of the formula I ##STR2## where R¹ is C₁ -C₅ -alkyl, R² is hydrogen, C₁ -C₄ -alkyl or C₁ -C₄ -alkoxy, R³ is hydrogen, halogen, cyano, aryl or aryloxy, the aromatic ring being unsubstituted or substituted by one or more of the following radicals: C₁ -C₆ -alkyl, C₂ -C₄ -alkenyl, C₁ - or C₂ -haloalkyl, C₁ -C₆ -alkoxy, C₁ -C₄ -alkoxy-C₁ -C₄ -alkyl, aryl, aryl-C₁ - or C₂ -alkyl, aryloxy, aryloxy-C₁ -C₄ -alkyl, aryloxy-C₁ -C₄ -alkoxy, haloaryloxy-C₁ -C₄ - alkoxy, halogen, halo-C₁ -C₄ -alkoxy, C₁ -C₄ -alkylthio, thiocyanato, cyano and nitro, or R³ is hetaryl adamantyl fluorenyl or C₃ -C₇ -cycloalkyl or C₅ - or C₆ -cycloalkenyl, the radicals being unsubstituted or substituted by C₁ -C₄ -alkyl (methyl or ethyl), halogen (chlorine or bromine), C₁ - or C₂ -haloalkyl (trifluoromethyl, tetrabromoethyl or dichlorodibromoethyl), C₃ - or C₄ -alkenyl (methylvinyl or dimethylvinyl), C₂ -C₄ -haloalkenyl (dichlorovinyl, dichlorobutadienyl, difluorovinyl or trifluoromethylvinyl), methoxycarbonyl-C₃ - or C₄ -alkenyl (methylmethoxycarbonylvinyl), cyclopentylidenemethyl, halophenyl (chlorophenyl), C₁ - or C₂ -alkoxyphenyl (ethoxyphenyl) or C₁ -C₄ -alkylphenyl (tert-butylphenyl), X is straight-chain or branched, saturated or unsaturated C₁ -C₁₂ -alkylene which is unsubstituted or substituted by halogen or hydroxyl, and n is 0 or 1, have an excellent fungicidal action.

Where n is 0, X_(n) is a single bond.

Because of the C═C double bond, the novel compounds of the formula I are obtained in their preparation as E/Z isomer mixtures, which can be separated into the individual components in a conventional manner, for example by crystallization or chromatography. Both the individual isomeric compounds and their mixtures are embraced by the invention and can be used as fungicides.

The novel compounds of the formula I can be prepared, for example, by reacting an ortho-substituted benzyl bromide of the general formula III, where R¹ and R² have the abovementioned meanings, with an alkali metal salt, alkaline earth metal salt or ammonium salt of a carboxylic acid of the formula II, where R³, X and n have the abovementioned meanings, in a solvent or diluent and with or without the addition of a catalyst to give the novel compounds. ##STR3##

The preparation of carboxylic esters from alkyl halides and carboxylates is known (cf. for example Synthesis 1975, 805).

Examples of suitable solvents or diluents for the reaction of II with III are acetone, acetonitrile, dimethyl sulfoxide, dioxane, dimethylformamide, N-methylpyrrolidone, N,N'-dimethylpropyleneurea and pyridine.

It may also be advantageous to add a catalyst, e.g. potassium iodide or tetramethylethylenediamine, to the reaction mixture in an amount of from 0.01 to 10% by weight, based on compound III.

The corresponding reactions can also be carried out in a two-phase system (e.g. carbon tetrachloride/water). Examples of suitable phase transfer catalysts are trioctylpropylammonium chloride and cetyltrimethylammonium chloride (cf. Synthesis 1974, 867).

The carboxylates of the formula II are known. They can be prepared from the corresponding carboxylic acids using bases (e.g. potassium hydroxide) in an inert solvent (e.g. ethanol).

The ortho-substituted benzyl bromides of the formula III can be prepared by reacting a known α-ketocarboxylic ester of the formula IV (cf. for example J. M. Photis, Tetrahedron Lett. 1980, 3539) ##STR4## with bromine in a solvent, for example tetrachloromethane, with or without exposure to a light source (e.g. 300 W mercury vapor , or with N-bromosuccinimide (Horner and Winkelmann, Angew. Chem. 71 (1959), 349) to give the α-ketocarboxylic esters of the general formula V, R¹ having the abovementioned meanings.

The α-ketocarboxylic esters of the formula V can be converted into the abovementioned ortho-substituted benzyl bromides of the general formula III in a Wittig reaction with an alkyl- or alkoxymethyltriphenylphosphonium bromide in the presence of a base, e.g. n-butyllithium, sodium methylate, potassium tert-butylate or sodium hydride (cf. G. Wittig and U. Schollkopf, Org. Synth., Coll. Vol. V (1973), 751-754).

The novel compounds of the formula I can be prepared, for example, by subjecting a novel α-ketocarboxylic ester of the general formula VI to a Wittig reaction with an alkyl- or alkoxymethyltriphenylphosphonium bromide in the presence of a base, e.g. n-butyllithium, sodium methylate, potassium tert-butylate or sodium hydride, R¹, R², R³, X and n having the abovementioned meanings: ##STR5##

The novel α-ketocarboxylic esters of the formula VI are useful intermediates. They can be prepared, for example, by reacting the abovementioned compound of the formula V with an alkali metal salt, alkaline earth metal salt or ammonium salt of a carboxylic acid of the formula II, where R³, R¹, X and n have the abovementioned meanings, in a solvent or diluent and with or without the addition of a catalyst, the product being a novel compound of the formula VI. ##STR6##

The preparation of carboxylic esters from alkyl halides and carboxylates is known (cf. for example Synthesis 1975, 805).

Suitable solvents or diluents for the reaction of II with V are acetone, acetonitrile, dimethyl sulfoxide, dioxane, dimethylformamide, N-methylpyrrolidone, N,N'-dimethylpropyleneurea and pyridine.

It may also be advantageous to add a catalyst, e.g. potassium iodide or tetramethylethylenediamine, to the reaction mixture in an amount of from 0.01 to 10% by weight, based on compound V.

The corresponding reactions can also be carried out in a two-phase system (e.g. carbon tetrachloride/water). Examples of suitable phase transfer catalysts are trioctylpropylammonium chloride and cetyltrimethylammonium chloride (cf. Synthesis 1974, 867).

In general terms the novel compounds are extremely effective on a broad spectrum of phytopathogenic fungi, in particular those from the class consisting of the Ascomycetes and Basidiomycetes. Some of them have a systemic action and can be used as foliar and soil fungicides.

The fungicidal compounds are of particular interest for controlling a large number of fungi in various crops or their seeds, especially wheat, rye, barley, oats, rice, Indian corn, lawns, cotton, soybeans, coffee, sugar cane, fruit and ornamentals in horticulture and viticulture, and in vegetables such as cucumbers, beans and cucurbits.

The novel compounds are particularly useful for controlling the following plant diseases:

Erysiphe graminis in cereals,

Erysiphe cichoracearum and Sphaerotheca fuliginea in cucurbits,

Podosphaera leucotricha in apples,

Uncinula necator in vines,

Puccinia species in cereals,

Rhizoctonia solani in cotton,

Ustilago species in cereals and sugar cane,

Venturia inaequalis scab) in apples,

Helminthosporium species in cereals,

Septoria nodorum in wheat,

Botrytis cinerea gray mold) in strawberries and grapes,

Cercospora arachidicola in groundnuts,

Pseudocercosporella herpotrichoides in wheat and barley,

Pyricularia oryzae in rice,

Phytophthora infestans in potatoes and tomatoes,

Fusarium and Verticillium species in various plants,

Plasmopara viticola in grapes,

Alternaria species in fruit and vegetables.

The compounds are applied by spraying or dusting the plants with the active ingredients, or treating the seeds of the plants with the active ingredients. They may be applied before or after infection of the plants or seeds by the fungi.

The novel substances can be converted into conventional formulations such as solutions, emulsions, suspensions, dusts, powders, pastes and granules. The application forms depend entirely on the purposes for which they are intended; they should at all events ensure a fine and uniform distribution of the active ingredient. The formulations are produced in known manner, for example by extending the active ingredient with solvents and/or carriers, with or without the use of emulsifiers and dispersants; if water is used as solvent, it is also possible to employ other organic solvents as auxiliary solvents. Suitable auxiliaries for this purpose are solvents such as aromatics e.g., xylene, chlorinated aromatics e.g., chlorobenzenes, paraffins (e.g.. crude oil fractions), alcohols e.g., methanol, butanol, ketones e.g.. cyclohexanone), amines (e.g., ethanolamine, dimethylformamide), and water: carriers such as ground natural minerals (e.g., kaolins aluminas, talc and chalk and ground synthetic minerals (e.g., highly disperse silica and silicates): emulsifiers such as nonionic and anionic emulsifiers e.g., polyoxyethylene fatty alcohol ethers, alkyl sulfonates and aryl sulfonates); and dispersants such as lignin, sulfite waste liquors and methylcellulose.

The fungicides generally contain from 0.1 to 95, and preferably from 0.5 to 90, wt % of active ingredient. The application rates are from 0.02 to 3 kg or more of active ingredient per hectare, depending on the type of effect desired. The novel compounds may also be used for protecting materials, e.g., on Paecilomyces variotii.

The agents and the ready-to-use formulations prepared from them, such as solutions, emulsions, suspensions, powders, dusts, pastes and granules, are applied in conventional manner, for example by spraying, atomizing, dusting, scattering, dressing or watering.

Examples of formulations are given below.

I. 90 parts by weight of compound no. 286 is mixed with 10 parts by weight of N-methyl-α-pyrrolidone. A mixture is obtained which is suitable for application in the form of very fine drops.

II. 20 parts by weight of compound no. 286 is dissolved in a mixture consisting of 80 parts by weight of xylene, 10 parts by weight of the adduct of 8 to 10 moles of ethylene oxide and 1 mole of oleic acid-N-monoethanolamide, 5 parts by weight of the calcium salt of dodecylbenzenesulfonic acid, and 5 parts by weight of the adduct of 40 moles of ethylene oxide and 1 mole of castor oil. By pouring the solution into water and uniformly distributing it therein, an aqueous dispersion is obtained.

III. 20 parts by weight of compound no. 286 is dissolved in a mixture consisting of 40 parts by weight of cyclohexanone, 30 parts by weight of isobutanol, 20 parts by weight of the adduct of 40 moles of ethylene oxide and 1 mole of castor oil. By pouring the solution into water and finely distributing it therein, an aqueous dispersion is obtained.

IV. 20 parts by weight of compound no. 286 is dissolved in a mixture consisting of 25 parts by weight of cyclohexanol, 65 parts by weight of a mineral oil fraction having a boiling point between 210° and 280° C., and 10 parts by weight of the adduct of 40 moles of ethylene oxide and 1 mole of castor oil. By pouring the solution into water and uniformly distributing it therein, an aqueous dispersion is obtained.

V. 80 parts by weight of compound no. 286 is well mixed with 3 parts by weight of the sodium salt of diisobutylnaphthalene-α-sulfonic acid, 10 parts by weight of the sodium salt of a lignin-sulfonic acid obtained from a sulfite waste liquor, and 7 parts by weight of powdered silica gel, and triturated in a hammer mill. By uniformly distributing the mixture in water a spray liquor is obtained.

VI. 3 parts by weight of compound no. 286 is intimately mixed with 97 parts by weight of particulate kaolin. A dust is obtained containing 3% by weight of the active ingredient.

VII. 30 parts by weight of compound no. 286 is intimately mixed with a mixture consisting of 92 parts by weight of powdered silica gel and 8 parts by weight of paraffin oil which has been sprayed onto the surface of this silica gel. A formulation of the active ingredient is obtained having good adherence.

VIII. 40 parts by weight of compound no. 286 is intimately mixed with 10 parts of the sodium salt of a phenolsulfonic acid-urea-formaldehyde condensate, 2 parts of silica gel and 48 parts of water to give a stable aqueous dispersion. Dilution in water gives an aqueous dispersion.

IX. 20 parts by weight of compound no. 286 is intimately mixed with 2 parts by weight of the calcium salt of dodecylbenzenesulfonic acid, 8 parts by weight of a fatty alcohol polyglycol ether, 2 parts by weight of the sodium salt of a phenolsulfonic acid-urea-formaldehyde condensate and 68 parts by weight of a paraffinic mineral oil. A stable oily dispersion is obtained.

In these application forms, the agents according to the invention may also be present together with other active ingredients, for example herbicides. insecticides, growth regulators, and fungicides, and may furthermore be mixed and applied together with fertilizers. Admixture with other fungicides frequently results in an increase in the fungicidal spectrum.

USE EXAMPLE 1 Action on wheat brown rust

Leaves of pot-grown wheat seedlings of the "Fruhgold" variety were dusted with spores of brown rust (Puccinia recondita). The pots were then placed for 24 hours at 20° to 22° C. in a high-humidity (90-95%) chamber. During this period the spores germinated and the germ tubes penetrated the leaf tissue. The infected plants were then sprayed to runoff with aqueous liquors containing dry basis) 80% of active ingredient and 20% of emulsifier. After the sprayed-on layer had dried, the plants were set up in the greenhouse at 20° to 22° C. and a relative humidity of 65 to 70%. The extent of rust fungus spread on the leaves was assessed after 8 days.

The results show that active ingredients 286 and 316, applied as 0.025 wt % spray liquors, have a better fungicidal action (90%) than the prior art active ingredients A (35%) and B (35%).

USE EXAMPLE 2 Action on Pyricularia oryzae (protective)

Leaves of pot-grown rice seedlings of the "Bahia" variety were sprayed to runoff with aqueous emulsions containing dry basis) 80% of active ingredient and 20% of emulsifier, and inoculated 24 hours later with an aqueous spore suspension of Pyricularia oryzae. The plants were subsequently placed in a climatic cabinet at 22° to 24° C. and a relative humidity of 95 to 99%. The spread of the disease was assessed after 6 days.

The results show that active ingredients 286, 83, 178 and 513, applied as 0.05% spray liquors have a better fungicidal action (97%) than prior art active ingredient A (55%).
